Title:
SYSTEM FOR HYDROGEN CHARGING
Document Type and Number:
WIPO Patent Application WO/2011/138826
Kind Code:
A1
Abstract:
Disclosed is a system for hydrogen charging which includes, as a flow control part, an orifice (120) disposed between a hydrogen charging port (20) and a hydrogen tank (52) having a large value of heat flux. No orifice is disposed on the side of a hydrogen tank (50) having a small value of heat flux. The orifice (120) has the function of increasing channel resistance. Thus, the hydrogen tank (50), which has a small heat flux value, can be first brought into a fully charged state, and the hydrogen tank (52), which has a large heat flux value, can be subsequently brought into a fully charged state. Alternatively, the system may have a configuration that includes, as flow restriction parts, a check valve having a cracking pressure of ΔP2 disposed on the side of the hydrogen tank (52), which has a large heat flux value, and a check valve having a cracking pressure of ΔP1 disposed on the side of the hydrogen tank (50), which has a small heat flux value, where ΔP2>ΔP1.
